Numerical and Experimental Investigation of Nonlubricated Air Scroll Expander Derived From a Refrigerant Scroll Compressor

Abstract

additional advantages when it comes to replacing equipment in automobiles for smooth, frictionless operation (Fatigati et al., 2022). They can also work in both dry and wet conditions, which is useful in heat-generating applications.The operation of the scroll machine is very simple and makes its simplicity a major factor in many industries. The other factors like compactness and durability are the added advantages of the scroll machine. These factors make it a viable choice as an expander in various industries including small-scale ORC systems (Fatigatib, 2020). The scroll expander was divided into three major categories like hermetic scroll-type expanders, semi-hermetic scroll-type expanders, and open scroll-type expander drive expanders were studied in the literature study done by Fatigatib (Fatigatib, 2020) in the year 2020. A review by Fatigatib (Fatigatib, 2020) , studied a small-scale ORC-based test bench. The working fluid considered in the study is R134a for debuting a hermetic scroll expander. The scroll-type expander used in the study is derived from a compressor and used three poles asynchronous engine for integrating the hermetic scroll-type expander developed. Literature ReviewScroll expander application in the automobile industry has been tested (Fatigati et al., 2022). In this research, the scroll expander's feasibility as a dual intake port is analyzed. Similarly, research on a large number of micro-to small-scale organic Rankine cycle (ORC) applications are Frontiers in Heat and Mass Transfer
